Despite predictions to the contrary, 2014 was a good year for Class A apartments in the DC region, according to a year-end report from real estate research firm Delta Associates released late Monday.

With an influx of new inventory hitting the market, developers had predicted slowdowns in rent growth in 2014. But instead, a growing population of millennials in the District ensured that overall, rent grew in the region by 1 percent. High-rise rent prices ticked down, but only slightly; low-rise rents rose enough to balance that out. The absorption of new units was “record-setting,” Delta said, with 11,237 Class A apartments absorbed during the year.

Vacancies among Class A rentals did increase to 5.6 percent thanks to the large amount of new inventory coming online; 14,286 units were delivered in 2014. An additional 32,131 units are currently under construction in the DC area.

Amid all that competition for pricey units, Delta did see one trend: A rise in demand at both extremes of the market.

“The marketplace is bifurcated,” Delta said. “There is a flight to both quality (high end Class A units) and value (Class B product or shared Class A units).”

Demographic and housing trends will power a healthy apartment market over the next five years or more. Due to a confluence of factors, including the Millennial demographic bulge and the increased preference to rent rather than own following the national housing collapse, there is an extremely large cohort of renters expected to emerge that will increase in size for another decade.
